Gold iPhone sold out til October

Early buyers of the iPhone 5S, which went on sale Friday morning, appear to be overwhelmingly choosing choosing the gold-colored model over the two other color options.

People trying to buy a gold phone in Apple's online store Friday saw a message stating the phone will not ship until October. By contrast, Apple said the silver and "space gray" models will be shipped in 7 to 10 business days. That's true for all three varieties of the phone, with 16GB, 32GB, and 64GB of storage.

Anecdotal reports from lines of shoppers outside Apple stores Friday also showed big demand for the gold-hued phones, which Apple is offering for the first time.

"It's new and shiny," explained Georgia Tech student Chance Shafor, 22, who was the first in line Friday morning outside an Apple store at Lenox Square mall in suburban Atlanta. Shafor said he was planning to get the gold version, as were most of the other buyers interviewed outside the store by CNN.

In China, the iPhone 5S has been available for preorder since Tuesday. Chinese news outlets reported that retailers have already sold all of the gold iPhone 5S models they had in stock. Gold is a wildly popular color in China and India, countries where Apple is hoping to capture a larger slice of the smartphone market.

Unlike past models of the iconic smartphone, the iPhone 5S does not come in black or white.

"Gold is a popular choice in many markets, particularly in Asia where Apple has a stated goal of growth," said Massimiliano Pogliani, CEO of luxury phone company Vertu, in a recent e-mail to CNN. "Gold is a colour that is always in demand, whether for jewelry, watches or fashion."

The iPhone 5S went on sale Friday in 11 countries and territories along with the iPhone 5C, a cheaper, plastic-encased model that comes in five bright colors. The higher-end 5S has and upgraded camera, faster processor and a new fingerprint sensor for improved security.

Apple could be facing tight supplies of the iPhone 5S. According to 9to5Mac and AllThingsD, sources from U.S. carriers are reporting that their stock of the phones is limited. According to All Things D, AT&T will reserve the gold and silver models for its online sales.

Unlike the 5S, the cheaper iPhone 5C was available for presale online, and so far Apple, wireless carriers and other vendors still have the devices in stock in the U.S. Apple has not released any numbers on pre-orders.

The phones went on sale Friday in the United States, Australia, Canada, China, France, Germany, Hong Kong, Japan, Puerto Rico, Singapore and the United Kingdom.

Gene Munster, an analyst at Piper Jaffray, predicts that Apple will sell between and 6 million iPhones around the world during the three-day launch weekend and that it will sell out of iPhone 5S devices completely. He said that Apple will likely move 3 million iPhone 5C models over the weekend.

Some suspect the anticipated sellout is a reason Apple did not make the iPhone 5S available for presale online.
